Also, maybe we can make it an out-of-line thing rather than an inline?

Why not just make it

	extern void wake_up_nested[_poll](wait_queue_head_t *,
		[unsigned long pollflags, ] unsigned int nesting);

and then just move it out of a header file entirely by writing it as a 
real function in some *.c file that only gets compiled with 
DEBUG_LOCK_ALLOC.

Hmm? No include hell.
